Find my discussion. Why did I create it for solution but nobody read?

Hello guys,
This bug took me days to find the way to fix it, and finally, I had given up until I found this link in reddit: https://github.com/jshackles/idle_master_py/blob/master/Documentation/Setup%20Instructions%20-%20Start%20Here.pdf

But before you follow the instruction in the link, you need:
-Sign in your steam account on both Google Chrome and Steam
-Open Idle Master and choose File --> Settings
-Look for the Lock symbol at the bottom left
-Click at the Eye symbol to edit.
-Follow the instruction in the link I gave above.
-Have fun :D

Follow these steps and I fixed it. Cheer! https://github.com/jshackles/idle_master_py/blob/master/Documentation/Setup%20Instructions%20-%20Start%20Here.pdf
